The psyllids or plant suckers are a group of sap

Sap is a fluid that circulates through a plant's vascular system, in a similar way to blood moving through our veins. Phloem sap carries the sugars produced in the leaves by photosynthesis down to roots and other storage organs, as well as carrying minerals and hormones. Xylem sap is watery and transports nutrients absorbed by the roots upwards to the rest of the plant. Some plants leak sap from wounds or pruning cuts, and this is known as bleeding. sucking true bugs (Hemiptera). There are more than 40 species found in Britain. Many species produce a white waxy secretion during the immature (nymph) stages and some cause distortion and galling to host plants. Most however, do not cause any significant damage to garden plants. More information on Psyllids from Britain can be found at .
